of this secondary radiation. In order to study the directionality of this effect, Cerenkov designed the experimental setup illustrated in Figure 2 using a conical mirror that reflected incoming radiation against a photographic plate located above a fluid-filled vessel. Photographs of the reflected light represent cases of ordinary luminescence
